The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of 2 formulations of a non-typable Haemophilus influenzae and pneumococcal candidate vaccine in young adults. Subjects will be vaccinated 2 times in an observer-blind manner with an interval of 2 months. The subjects receiving Engerix-B will receive in an open-manner a third dose of the vaccine at Month 6. The protocol posting has been updated following a protocol amendment.

Number of Subjects With Any Solicited Local and General Symptoms [ Time Frame: During a 7-day follow up period after any vaccination ] [ Designated as safety issue: No ]

Solicited local symptoms assessed were pain, redness and swelling. Any solicited local symptom was defined as occurrence of any solicited local symptom regardless of intensity grade.

Solicited general symptoms assessed were fatigue, gastrointestinal, headache, malaise, myalgia and temperature Any temperature was defined as oral temperature equal to or above (≥) 37.5 degrees Celsius (°C). For other symptoms: Any = any general symptom reported irrespective of intensity grade and relationship to vaccination.

Number of Subjects With Any Unsolicited Adverse Events (AE) [ Time Frame: During a 30-day (Days 0-29) follow up period after any vaccination ] [ Designated as safety issue: No ]

An unsolicited adverse event is any adverse event (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms will be reported as an unsolicited adverse event.

Number of Subjects With Any Serious Adverse Events (SAEs) [ Time Frame: From Day 0 to Day 420 ] [ Designated as safety issue: No ]

SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination.

Number of Subjects With Any Biochemical Laboratory Abnormalities [ Time Frame: During a 7-day follow up period after vaccine dose 1 and 2 and at Days 180, 300 and 420 ] [ Designated as safety issue: No ]

Abnormalities reported include values outside the normal ranges. Time points were presented as before (Pre) or after (Post) Dose 1, 2 or 3.

Number of Subjects With Any Hematological Laboratory Abnormalities [ Time Frame: During a 7-day follow up period after vaccine dose 1 and 2 and at Days 180, 300 and 420. ] [ Designated as safety issue: No ]

This outcome presents results for RBC, WBC High and Low, PLA and HEM. Time points were presented as before (pre) or after (post) doses 1, 2 or 3.

Number of Subjects With Any Hematological Laboratory Abnormalities [ Time Frame: During a 7-day follow up period after vaccine dose 1 and 2 and at Days 180, 300 and 420. ] [ Designated as safety issue: No ]

Concentrations were given as Geometric Mean Concentrations (GMCs). The cut-off values were 112 Luminex Units per milliliter (LU/mL) for Anti-PD, 391 LU/mL for Anti-PhtD and 591 LU/mL for Anti-Ply.

Mean Number of Influenza-specific Cluster of Differentiation (CD) 4 T-cells. [ Time Frame: Prior to first vaccination (Day 0), at 14 days post vaccination 1 (Day 14) and 2 (Day 74) and at Day 480. ] [ Designated as safety issue: No ]

Mean Number of Influenza-specific Cluster of Differentiation (CD) 8 T-cells. [ Time Frame: Prior to first vaccination (Day 0), at 14 days post vaccination 1 (Day 14) and 2 (Day 74) and at Day 480. ] [ Designated as safety issue: No ]

The mean number was calculated for CD8+ cells stimulated by protein D (PD), pneumococcal histidine triad D (PhtD) and pneumolysin toxoid (dPly) and expressing the following citokine combinations:

Subjects received 2 doses of adjuvanted Non-Typable Haemophilus influenza and pneumococcal vaccine GSK2254233A at Months 0 and 2. The vaccine was administered intramuscularly into the deltoid region of the non-dominant arm.

Biological: GSK2231395A

Two doses will be administered intramuscularly; one dose at Month 0 and the second dose a Month 2. Two different formulations of this vaccine will be tested.

Experimental: GSK2254232A Group

Subjects received 2 doses of non-adjuvanted Non-Typable Haemophilus influenza and pneumococcal vaccine GSK2254232A at Months 0 and 2. The vaccine was administered intramuscularly into the deltoid region of the non-dominant arm.

Biological: GSK2231395A

Two doses will be administered intramuscularly; one dose at Month 0 and the second dose a Month 2. Two different formulations of this vaccine will be tested.

Active Comparator: Engerix Group

Subjects received 3 doses of Engerix vaccine at Months 0, 2 and 6. The vaccine was administered intramuscularly into the deltoid region of the non-dominant arm.

Biological: Engerix-B

Two doses will be administered intramuscularly; one dose at Month 0 and the second dose a Month 2.

Detailed Description:

This Protocol Posting has been updated following amendment of the Protocol, January 2010. The sections impacted are: study design and study endpoints.

Written informed consent obtained from the subject.

Subject without medical history, clinical finding or laboratory finding, which, in the opinion of the investigator, could pose a safety concern or interfere with the protocol.

Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.

Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccines, with the exception of the influenza vaccine which can be administered >14 days prior to or >14 days following vaccine doses 1 and 2.

Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.

Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus infection.
